    Ich mag den Schlauch, bin aber auch nicht der Rad-Guru. Schlauch läuft aber gut und keine Probleme in Sachen Defekt oder Ähnliches.

    Ich bin auf der Suche nach - einigermaßen leichten - Schläuchen bei den Maxxis hängen geblieben und habe sie für eine Gravelbereifung mit Schwalbe G one Allrounder 700*40 verwendet. Das Ergebnis ist meiner Meinung nach sehr gut. Gewicht ist ok und sie halten wirklich lange die Luft. Bisher also kein Stress.
